Synopsis
A series of weak low pressure systems pass to the south of the
area through the weekend while high pressure remains centered to
the north. Low pressure will then be departing to the northeast
Monday as a canadian cold front passes through the area. High
pressure then builds into the region through Wednesday, moving
offshore Wednesday night into Thursday. Another frontal system
impacts the region at the end of next week.

Near term until 6 am Saturday morning
Increasingly unsettled conditions are expected as a closed upper
low slowly approaches from the southwest, and an upper trough
passes to the north. Weak disturbances ahead of the systems and
subtle isentropic lift in a warm advection regime will lead to
the continued development of intermittent rain and or drizzle
through the night, with mostly cloudy conditions as a subsidence
inversion remains. Have increased pops this eve and overnight a
bit based on latest trends in model guidance and radar imagery.

Once again, timing of any steadier or heavier precipitation has
slowed compared to previous forecasts and model runs. The upper
wave and attendant surface trough now moving through the eastern
canadian provinces is expected to quickly be moving east of the
area by morning, with confluent flow in its wake strengthening a
surface high to our north in response. With the building high,
any low pressure developing in association with the system to
the southwest is likely to be shunted more to the south, meaning
less precipitation overall for the area through at least
Saturday morning.

Temperatures this evening may be initially less certain with
mesoscale influences ongoing, such as a sound breeze at klga
which is leading to locally cooler temperatures across northern
queens. However, mild temperatures are expected to continue into
the night, with lows in the upper 30s to mid 40s - around 5 to
10 degrees above climatological normals.

Short term 6 am Saturday morning through Saturday night
The approaching upper low to the southwest becomes the dominant
system into the weekend, though attendant surface lows will
still likely remain shunted farther south of the area as high
pressure builds to our north. As a result, drier conditions than
forecast may be possible as lower dew points advect
southwestward.

Upper divergence then sharply increases into the night as the
system moves closer to the area, leading to better chances of
precipitation by morning.

Cloudy conditions should for the most part keep temperatures
above freezing, though portions of northern connecticut may come
close Saturday night. If these areas can fall below freezing
then freezing rain will be possible around sunrise. Expect
highs in the upper 40s to lower 50s, and lows in the 30s to
lower 40s.

Long term Sunday through Friday
A progressive and amplified long wave pattern will remain across the
country through the long term period. Split flow Sunday, with a
northern stream longwave trough moving through eastern canada and
the northeast, and a southern stream closed low moving across the
region, will become more phased Sunday night as the southern stream
low moves off the new england coast. The northern stream ridge will
be weakening as the southern low moves into the area, and the
surface high. There still remains some uncertainty as to how
quickly the high breaks down Sunday, and the timing of the low
moving into the region. Late Saturday night into Sunday morning
looks to be the best timing for the highest probabilities of
precipitation as the mid level low moves over the area at this time.

With strong lift with the low and the area in the left front region
of a 40 to 60 kt 850 jet, there will be the potential for a period
of moderate to briefly heavy rainfall. Also, there will be rather
marginal elevated instability, so a rumble of thunder can not be
ruled out. However, with the low chance and timing uncertainties will
not mention in the forecast. Warm advection in advance of the
southern stream low will allow thermal profiles to warm through much
of the atmosphere and all liquid precipitation is expected with the
series of lows into Sunday. Colder air will begin to be pulled into
the region later Sunday night as the low departs, however, at this
time the colder air will be confined to the northern zones with snow
and a snow rain mix as the low departs late Sunday night into Monday.

With the passage of the northern stream shortwave Monday into Monday
night and a canadian cold front passing through, the area returns to
below normal temperatures. Little moisture will accompany the
passage of the front Monday and will keep area dry. However, there
will be a chance of flurries across portions of the lower hudson
valley.

The longwave pattern remains progressive through next week. A lot of
uncertainty develops in the guidance from Wednesday through Friday,
with uncertainty in the timing of the high moving offshore and the
strength and timing of the next northern stream frontal system. May
be too quick to bring in chance of precipitation late Thursday,
however, mainly followed wpc guidance due to uncertainties.

Aviation 01z Saturday through Wednesday
Low pressure moving into the mid atlantic states tonight passes
well south and east in the morning. High pressure briefly follows
for Saturday afternoon before another wave of low pressure
approaches from the south late Saturday night.

Generally,VFR the first half of tonight with occasional MVFR
early in patches of light rain. Much of the guidance is supporting
improvement this evening, however, there is concern that these
lower conditions may be more prevalent than forecast.

Widespread MVFR conditions are forecast to redevelop after 06z
as a storm system passes to the south and east with a period
light rain, mainly near the coast in the morning.

Vfr conditions develop by afternoon and quite possibly sooner
should the rain remain south of the area as guidance continues
to trend.

Light SE at less than 10 kt become light and variable tonight.

N NE winds develop late morning into the afternoon, with a
period of 15 to 20 kt gusts possible for nyc nj metro terminals.

Ny metro enhanced aviation weather support...
